Struct SectionChain 

#[non_exhaustive]
pub struct SectionChain {
    pub points: Vec<Point2>,
    pub ends: Option<[ChainEnd; 2]>,
}

One plane-local cut polyline: closed, or open and ending on a region.

A closed chain’s terminal point is implicit and must not duplicate the first point.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

points: Vec<Point2>

Plane-local points in traversal order.

ends: Option<[ChainEnd; 2]>

What the first and last point end on; None for a closed chain.

Implementations

impl SectionChain

pub fn closed(points: Vec<Point2>) -> Self

pub fn open(points: Vec<Point2>, start: ChainEnd, end: ChainEnd) -> Self

Construct an open chain from what its first and last point end on.

pub const fn is_closed(&self) -> bool

Whether the last point connects back to the first.
